I hope you enjoyed yourself.  This is certainly not a critical issue.

I do use POP3, with the added wrinkle of going through POPFILE for spam  
filtering.  I will try this logging, but I also still need to do a  
"complete" test of sending myself a test with long headers, and  
capturing the file at each stage: unsent from draft folder, from sent  
folder, and then as received.  (also using different send and receive  
hosts)  The little testing I have done just left me more confused.   
Unfortunately, since I am now aware of it, as long as I can remember to  
check the TO: header before actually sending any reply, I can work  
around it.
